Answer:
The correct answer is Electrons.
Explanation:
<u>When a cell receives a glocusa molecule</u>, much of it converts it into energy and this helps it boost its metabolic reactions.
This energy is extracted by reactions called catabolic reactions, and during this reaction <u>the molecules break into smaller pieces.
</u>
While glucose is broken down into small pieces, energy is released in the form of ATP. Here the electrons found in glucose are transferred to small molecules called electron carriers, which are transported to a group of proteins found in the inner membrane of the mitochondrion, and it is called the electron transport chain.
<u>When electrons pass from one molecule to another</u> it is when cellular respiration is generated, and the reactions generated during this process are redox reactions.
